More pads from a VSTi. Be sure to play with special effects like wah wah and adjust the LFO, resonance, and wetness to really explore the palette. Here’s a sample of what you can accomplish with free software like Audacity.

I worked up some pads that would add some texture to a diverse range of tracks. These were created using a VSTi, recorded using VSTHost, and then effects applied in Audacity. Experimenting with sound effects is an excellent music production tip.

I came up with this kick drum for an industrial / progressive metal sound. You can use it in anything though. I created it in a VSTi through VSThost again. I did multiple effects using Audacity.

I am using this opportunity to share a bunch of drum sounds I made. These were made in Audacity by tweaking a WAV file I had made in VSThost using a VSTi.
